I just laughed when I saw your comment, and the bugzilla links are styled as "visted" (i.e. gray instead of black.) I hate that behavior. When I click in the address bar, it's because I want to edit the URL. If I want to go somewhere else, I'll open a new tab, or use a bookmark, or click a link on a page.
